Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often gets its power from X-rays, but the power can also come from protons or other types of energy.
The term "radiation therapy" most often refers to external beam radiation therapy. During this type of radiation, the high-energy beams come from a machine outside of your body that aims the beams at a precise point on your body. During a different type of radiation treatment called brachytherapy (brak-e-THER-uh-pee), radiation is placed inside your body.
Radiation therapy damages cells by destroying the genetic material that controls how cells grow and divide. While both healthy and cancerous cells are damaged by radiation therapy, the goal of radiation therapy is to destroy as few normal, healthy cells as possible.
Radiation oncology is a medical specialty that involves treating cancer with radiation. Doctors who specialize in treating cancer with radiation (radiation oncologists) use radiation therapy to treat a wide variety of cancers.
Radiation therapy uses carefully targeted and regulated doses of high-energy radiation to kill cancer cells. Radiation causes some cancer cells to die immediately after treatment, but most die because the radiation damages the chromosomes and DNA so that the cells can no longer divide and the tumor can't grow.
Radiation oncologists at Nova Global Healthcare treat malignant diseases and work closely with medical oncologists, surgeons and other doctors to coordinate the best care for you.
Radiation Oncology encompasses all aspects of research that impacts on the treatment of cancer using radiation. It publishes findings in molecular and cellular radiation biology, radiation physics, radiation technology, and clinical oncology.
The field of radiation oncology covers the integration of radiation therapy into multimodal treatment approaches. Radiation Oncology provides an open access forum for researchers and clinicians involved in the management and treatment of cancer patients, bringing together the latest research and advances in the field. Advances in treatment technology, as well as improved understanding of the underlying biological resistance mechanisms, will further strengthen the role of radiation oncology.
